- Fixed a false positive in :doc:`readability-non-const-parameter
<clang-tidy/checks/readability-non-const-parameter>` when the parameter is referenced by an lvalue
+- Fixed a crash in :doc:`readability-suspicious-call-argument
+ <clang-tidy/checks/readability-suspicious-call-argument>` related to passing
+ arguments that refer to program elements without a trivial identifier.
Removed checks
